The lower leg component consists of the brace ankle joint, two adjustable
bars (1) and the strap (6). 2 Allen head screws (5) are used to adjust the
lower leg component.
3 Intended use
3.1 Indications for use
The brace is intended
exclusively
for orthotic fittings of the lower limbs and
exclusively for contact with intact skin.
The brace must be used in accordance with the indications.
3.2 Indications
• Unicompartmental knee osteoarthritis
• Pre-operative: Checking the indication of a valgizing corrective osteoto­
my in case of varus gonarthrosis (brace test)
• Post-operative: After intervention in the cartilage structure and meniscus
surgery requiring unilateral relief
The indication must be determined by the physician.
3.3 Contraindications
3.3.1 Absolute Contraindications
None known.
3.3.2 Relative Contraindications
The following indications require consultation with a physician: skin dis­
eases/injuries; inflammation; prominent, swollen scars; reddening and
hyperthermia of the treated limb; pronounced varicose veins, especially with
impaired return flow; lymphatic flow disorders, including unclear soft tissue
swelling distal to the body area where the device will be applied; sensory
and circulatory disorders in the legs, e. g. associated with diabetic neuropa­
thy.
3.4 Mechanism of Action
The brace reduces or increases the varus moment on the knee joint depend­
ing on the chosen brace.
In the treatment of medial knee osteoarthritis (brace bar lateral), two mecha­
nisms cause a reduction in varus moment. Initially the rigid bridging of the
ankle joint in the frontal plane reduces eversion in the lower ankle joint. At
the same time, forces that can be adjusted at the lateral contact point of the
brace are transferred in the area of the lower leg. This effect shifts the
ground reaction force laterally. Immediate consequences are the reduction
of varus moment and relief for the medial compartment. In the treatment of
